E LY, or ,nnTnolT, MICHIGAN, AssIsnon To DETROIT STEEL PRODUCTS COMPANY, OF DETROIT, MICHIGAN, A CORPORATION or MICHIGAN WINDOW OPERATING MECHANISM Application filed September 16, 1-929. Serial No. 392,995.

The invention relates to window operating mechanism and refers more particularly to operating mechanism for a ventilator of an inteltiorly screened frame. :One of the ;ob-

jects of the invention is to so construct the opcratingmechanism that the aper ur in th screen for the operating mechanism is closed without the necessity of an extra shutter. Another object is to provide an improved 1 operating {mechanism with novel means for locking the operating rod in its Various positions. With these as Well as th r o je ts in view, the invention resides in the novel features of construction and combinations and arrangements of parts as more fully hereinafter set forth.

In the drawings Figure 1 is an interior elevation {of s, screened window having an operating mechanism embodying my invention;

Figures 2 ail-d3 are cross sections on the lines 22 and 3-3 respectively of Figure 1;

Figures 4 andfi are cross sections on the lines Hand 5 5 respectively of Figure 2 Figure 6 is a view similar to Figure ;1, showing, a modification;

Figures 7 and :8 are cross sections on the lines 7-47 and .8.8 respectively of Figure Figure 9 is an enlarged sectional elevation of a portionofthe mechanism;

Figure .10 is an end elevation thereof.

As shown in'Figures 1 to .5, inclusive, 1 is the frame, 2 is the vertically pivoted ventilator for the frame openin-gand 3 is the screen for the frame opening. This screen is located at the inner side of the frame '1 and is socured thereagainst. The lower portion of the lower bar 4 of the screen has the notch or opening 5 for the passage of the mechanism for operating the --ventil-ator.

The operating mechani-smgcomprises the support 6 extending longitudinally of the lower .bar of the frame land secured thereto bythe screw-s7. This support extends transversely of the frame and inwardly and is formed with the notch ;8 to receive the lower bar 4 of the screemthe support registering with the port-ion: ofcthe-lower har having the notch or cpen ingifi. 9 is i-thelopenating rod 50 having the handle 10 secured to oneiof its ends and pivotally connected at the other of its ends to the bracket 11, which latter is socured to the lower bar of the ventilator by the screws 12. This operating rod is longitudinally slidably mounted in a transverse opening 13 in the cylindrical guide 14, which is housed within the support 6 and ournalled therein at its upper and lower ends. This guide is located at one of the inner corners of the support, the upright wall of which is flanged inwardly at 15 and 16 to terminate adjacent diametrically opposite points of the guide, the portion of the upright wall between the flanges being .apertured and the operat? ing rod extending through this aperture.

The operating rod 9 is provided with the downwardly opening longitudinally spaced recesses 17 for. alternatively receiving the upper end of the pin 18 in the guide 14, whereby the operating rod may be held in various positions of longitudinal adjustment. 19 is a .bowed spring extending within the trans- Verse opening 13 of the guide above the operating rod and bearing on the latter to force the same toward the pin. By lifting the operating rodit may be released from the pin, after which the operating rod may be adjusted to adjust the ventilator.

WVith this construction, the support for the operating mechanism forms a housing for a part ofthe operating mechanism. The housing and the guide for the operating rod close the screen .lopeningthrough which the operating mechanism is adapted to extend. The guide is rotatable so that the operating rod-has both a lever and asliding action.

In the modification shown in Figures 6 to 10, inclusive, the ,windowand screen construction is substantially the same as that of Figures 1 to 5, inclusive. The support 20 is generally similarto the support (Sand is secured to the frame in the same manner.

The operatingrod 21 has fixedly secured to I oneendthehandle 22 and rotatably secured to the other end the coupling 23 which is pivotally connected to the bracket 24 upon the ventilator. 25 is thecylindrioal guide corresponding to the guide 14 and journalled at its upper and lower ends in the support 20 near one of its inner corners. This guide 25 is provided with a transverse opening which has the end portion 26 threaded and the intermediate portion 27 tapered from the threaded end portion. 28 is a collar having a polygonal (square, as shown) opening for sleeving over the operating rod 21. The end portion 29 of this collar is threaded to engage the threaded end portion 26 and the other end portion 30 is formed of tapered or wedge-shaped segments separated by the sawcuts 31. The tapered end portion 30 is adapted to engage the taperedintermediate portion 27 upon turning the collar in one direction and to be clamped thereby upon the operating rod. The turning of the collar may be accomplished by the turning of the operating rod about its longitudinal axis.

With the construction as above described, it will be seen that I have provided a simple and effective construction of mechanism for operating the ventilator. Also that I have provided a simple means controlled by the operating rod for locking the operating rod in its various positions of longitudinal ad-- justment.
